Every house has a different type of plumbing done. It maybe different in fixtures, the manner in getting the water in and types of pipes that make up the system. Water hammering, unfortunately, is a common problem in today’s households.
What is water hammering?
Water hammering, officially known as hydraulic shock, is when a wave of pressure or a surge like thing occurring when water or any other liquid, or even gas, in movement, is forced to change its direction or halt altogether. It is a “motion” or a momentum change. This happens when a tap or faucet closes abruptly at the end of a pipeline. By that a wave of pressure is spread within the pipeline. It can cause key problems, from clamor and clatter to vibration and collapse of the pipe, making things worse. This phenomenon actually has a very long history. From Roman empire to France and England, people had faced this issue and sought answers.
When does this occur?
In households, water hammering can occur when the washing machine, dishwasher or even a toilet closes off the flow of water suddenly. This may result in a very loud noise, a bang. It can be repetitive as the wave of the shock is transported from end to end within the plumbing system. The same can also be heard as a sort of shuddering. An explosion can occur when a valve is closed downstream and water attempts to flow as normal. Sometimes, air vents are included to prevent this from happening. It is takes place more commonly in pipes that are downhill sloped. If an explosion happens, do not wait but contact the guys today of a reputed plumbing company to take care of it.
How to prevent?
How can we reduce the effects of this scenario? Water hammer pulses can be lessened by surge tanks, accumulators, blow-off valves, expansion tanks and such other similar features. Shorter lengths of the pipelines also are a measure to prevent it. By reducing water pressure also, you can achieve a positive result. It can be done by fitting a regulator valve. Valves which are slowly closing and pipelines with good control in shutting down and starting up procedures can reduce the risk of water hammering as well. Water towers, which are mainly used in drinking water schemes, can also help keep a stable flow which can negate a larger pressure build up. A “hydropneumatics” maneuver, which works like a shock absorber in vehicles, if installed among the pipe and the machine, will absorb any shocks and cease banging.
Water hammering may not be something you are familiar with if you are not a plumber. Nevertheless, these precautions are worth taking without waiting to find out.
